======Tiled Code Generator======
Tiling is an important program transformation that is used to improve data locality and parallelization granularity. We provide a tiled code generator that produces tiled code with wavefront parallelization supported for the shared memory machine. 

===Usage===
Let's use the classic matrix multiplication as an illustration example, whose alphabets code is the following:
<sxh alphabets; gutter:false>
affine matrix_product {P, Q, R|P>0 && Q>0 && R>0}
       given  float A {i,k| 0<=i<P && 0<=k<Q};
              float B {k,j| 0<=k<Q && 0<=j<R}; 
     returns  float C {i,j,k| 0<=i<P && 0<=j<R && k==Q};
using
   float temp_C {i,j,k|0<=i<P && 0<=j<R && 0<=k<=Q};
through
   temp_C[i,j,k] = case
                      {|k>0}  : temp_C[i,j,k-1] + A[i,k-1]*B[k-1,j];
                      {|k==0} : 0; 
                   esac;
   C      = temp_C;
.
</sxh>

The tiled code generator is called through ScheduledC, therefore, the first step for the code generation is the same with ScheduledC -- specify spacetime map and memory map.
